To better serve you, we would like to discuss your specific requirement, Please Contact Us for a quote.
Undoped YVO4 is an excellent newly developed birefringence optical crystal .
- It has very good transmission in a wide wavelength range from visible to infrared.
- It has large index of refractivity and birefringence difference.
- Compared with other important birefringence crystals, YVO4 has higher. hardness, better fabrication property, water insoluble and man-made than calcite (CaCO3 single crystal).
- Easier to get large, high quality crystal and lower cost than rutile (TiO2 single crystal).
Those outstanding properties make YVO4 very important birefringence optical material and widely used in opto-electronic research, development and industry. For example, the optical communication system needs a huge quantity devices of undoped YVO4, such as fible optical isolators, circulators, beam displacers, Glan polarizers and other polarizing devices.
